ECC (formerly Everything Claude Code) is an open-source repository of modular configurations, skills, instincts, hooks, and security guardrails for AI coding assistants. It provides battle-tested harness setups designed to optimize performance across Claude Code, Codex, Cursor, Gemini, and related agent tools.

What it's for

  • Configure custom skills and automated hooks for Claude Code without starting from scratch
  • Standardize AI agent rules, memory instincts, and guardrails across dev team environments
  • Deploy pre-built MCP and plugin integrations into AI coding assistants like Cursor and Claude

Features

  • Modular skill definitions covering over 100 domain-specific developer capabilities
  • Automated hooks and commands for common development workflows
  • Multi-tool harnesses supporting Claude Code, Cursor, Codex, OpenCode, and Gemini
  • Security guardrails and audit scripts to prevent unintended agent actions
  • Instinct and memory templates to preserve context across long-running sessions
